Ticha and M. Tichy at Klet. The International Year of Astronomy (IYA 2009) is a global effort initiated by the IAU and UNESCO to stimulate worldwide interest in astronomy under the central theme "The Universe, Yours to Discover". The IYA celebrates the 400th anniversary of the first use of an astronomical telescope.
